Convenient switch hides an inconvenient truth

Re: Sounds familiar...

You set up exclusions?

Why would you do something as evil as that?

You should set up dummy reservations, and write in the comment why it's reserved.

(Unless you ran a DHCP server where you could add a comment to exclusions, of course. )

Exclusions tends to stick around a long time after the device is retired. And without a good comment or other documentation, no one will dare removing it.

Oslo clever clogs craft code to scan di mavens and snare dodgy staff

Well, I doubt there's a University in Oslo, Marshall County, Minnesota, but still...

And Oslo Community, in Dodge, Minnesota is even less likely since they don't even have a Post office any more...

Re: Find it difficult to believe

It's not so difficult to believe...

The pads were used by embassies and such, as they often have a need to confer with home over a secure channel, knowing that anyone could be listening in on the conversation.

Spies would mostly try to avoid any situation whereeven part of the conversation could be captured, as not only the message, but also the sender and receiver would be secret.

OTPs and other codebooks is something you'd expect to find in an embassy or in the comms on a battleship, but not in someone's home. It's also very difficult to transfer a code books and OTPs to field agents without them being compromised.

BOFH: Is everybody ready for the meeting? Grab a crayon – let's get technical

Re: A good title for that documentation is ...

No, a BOM is a general use manual, probably explaining best practises for using electric cattleprods and best impact points on a cranium. You know, the stuff that's the same on every site.

What he was writing is the BSM - Bastard Site Manual, because it mostly deals with site-specific issues and resources.

Re: Are PDAs still alive?

Palm? Windows Immobile?

Real BOFHs used Psions...

If you couldn't run a terminal emulator on it and hook it up to a console port on a Switch, Router or 'that weird box' in the corner, what use was it anyway?

The Psions had the terminal emulator and rather nifty scripting functions.

Add the WYSIWYG word processor, spreadsheet and DBs, and you had all your important documentation in your pocket.

The modern replacement is the Planet Computers Gemini clamshell which is Dual or even Tripleboot...

(Android and Debian, and possibly also Sailfish or whatever floats your boat)

Mine only runs Android... yet...

And yes, the keyboard is just as good as on the Psion S5 series.

I've been told that the RNoAF lost an F5 once(or was it an earlier jetfighter?) because a spannermonkey had lost the correct bolt to mount the brake chute, and picked a random bolt of the same diameter.

It would have gone unnoticed, except the pilot accidentally triggered the chute while still in the air.(the handle is supposedly next to the gear retraction handle). He wanted to lower the gears as he was preparing to land, released the chute instead, and when he tried to eject the chute, nothing happened...

He was forced to eject as the plane was becoming uncontrollable, and both he and the plane ended up in the ocean off the coast somewhere.

EmDrive? More like BS drive: Physics-defying space engine flunks out

Trygve Henriksen

Re: 'Ye cannae break the laws of physics!'

No, the Big Bang did NOT break the laws of physics.

The laws we know of now were very, very different during the BB, and they changed as the Universe formed and began expanding.

If something doesn't match the laws of Physics as we know them, there's either a failure to observe, or our interpretation of those laws is flawed.

Fixing a printer ended with a dozen fire engines in the car park

Trygve Henriksen

Re: Fire Safety Training

According to a firefighter that came around to Our Office, most extinguishers were only used to draw a line from where it was stored to where the fire started.

From a investigative viewpoint it's Nice to know where the fire started or was first observed, but for firefighting it was kind of useless.

(Lots of People grab the extinguisher, pull the safety and squeeze the trigger BEFORE moving towards the fire. )

He also told us that we might as well replace any powder-based ones with foam. Sure, they're less effective, but they doesn't damage everything the fire doesn't destroy, either.

As for only using it to secure a way out. Yeah. 'A building can be rebuilt,' is the usual answer. They'll also admit to not particularly enjoying searching for unconscious people or finding dead ones afterwards.

Get out and do a headcount, and the firefighters will love you.

You actually use paper tickets still?

Even here in Norway we can buy railway tickets on the mobile, and show them to the conductor.

(Though, I wouldn't be surprised if one of those tried to punch a hole in my phone... )

Frankly, if I worked as a teller on a trainstation, I'd be a lot more interested in doing great service, because most of the job can be replaced with an app...

Re: Keep old drives

One of every drive?

Sure, that will work if it's old Tandberg SLR drives, but what if it's DAT or 8mm video tapes?

(Yes, both of those have been used for backup purposes. DAT tends to stretch the tape in such a way that a tape will only ever be reliably read on the original drive, and 8mm... the less said... )

DLT and SDLT...

There are some that thinks the S stands for 'super'... Yeah...

I have half a dozen of those stashed away. One with a tape still stuck in it.

Odds are that none of them works any more.

I have Zip drives(still more reliable than DLT... ), Jaz, Clik! (or whatever it was named. )...

I could use a Bernoully drive, though.

If they were LJ II & III then the reason the wheels were worn down is that those printers were slow, and the users impatient, and they tended to DRAG the last of the sheet out of the printer.

Trust me, I KNOW this.

Nothing else could kill these beasts.

(That goes for the Canons and others also based around the same engine. Actually, a Canon engine)

Re: Engines

I did a partial rebuild of the 1.4i (Citroën TU3JP4) in my car(new headgasket, two new cylinder sleeves, piston rings, big-end bearings, and even reseated the valves.) a while ago. Then replaced the rear axle assembly and recently swapped out the old clutch(full kit).

I there's an instruction book around I can probably fix it.

I think... I still haven't fixed the old PFAFF sewing machine I rescued at the dump.

(It just needs a thorough clean and adjusting. I have found a service manual, but then there's the time... )

Re: 4" drives exist.

But only a few drives were ever sold back then, and even if the user in question actually DID use it, there's no way to make a more recent computer accept that drive.

That said, if anyone happens to have one laying about... I wouldn't mind getting my clammy hands on it.

Drone crashes after operator failed to spot extra building site crane

Trygve Henriksen

I notice that he claims expertise in GPS and that it simply cannot be more accurate than 50meters...

A 50 meter accuracy is so piss poor that it would be unusable for anything on a drone. With the clear acrea in his picture I'd expect better than 10meter, closing on 3.

He was flying it manually, in P-GPS mode, which means he should have had visual control of the drone.

How could he not see the tree he claimed his drone smashed into?

I think he got what he deserves; nothing!

I'm pretty certain that people who run that kind of operation can afford drones with directional antennas.

Every spy shop is aware of 'sidechannel' attacks and will have at least some defenses against them.

That was pretty much explained to them when they learned that you could pick up transmissions from an unshielded monitor and cable.

Ah, but if it's far away and maneuvering for a shot, the picture will shift and cause large changes to the image. Or there may be a car passing through its field of view.

you need to be really certain that the change in the data stream is caused by your event. That means running the event multiple times.

And in a counter-espionage scenario that is bad because it increases the chance that the observer catches on to what is happening.

Me?

I bought a CO2-powered airgun with 12 round magazine.

Except...

Drones such as the DJI Mavic transmits constantly, even when not recording.

All you're proving is that you're in the drone's Field of View, not that they're actively recording.

And since the Mavic has a pretty decent camera(4K video) it could actually be quite a distance away, setting up for a overview shot of the neighbours house before they put it up for sale because they want to get away from their paranoid neighbour.

You designed the computer room wrong.

The doors need to be 2" wider than any unit to be placed inside(usually the racks) and no more. The room needs to be long and narrow, and the racks facing towards one of the long walls, so that there's decent working area in front and behind, but no more. Workdesks and storage is to be at the end furthest away from the doors.

You need a raised floor, and a step up just inside the door. And a ramp that is cumbersome to assemble and put in place, and must be removed again to close the door.

That will make it a PITA to store large objects in there...

Mark off any corner or other floorspace with yellow and black tape, and write 'for recycling'...

Then track down and... 'no one ever heard from them ever again' anyone who has access without a good cause.

BOFH: Oh go on. Strap me to your Hell Desk, PFY

Electrically adjusted desks...

I have one of those at the office. It's a pretty big one, too...

I use the adjustments in the summer only.

In the evening I raise it to the top, then slip under it to reach the handle on the window so I can close it. (Desk is too wide to reach by leaning over it without risking to topple over. and the monitors are also in the way)

Then in the morning the next day I slip under again, open the window, get back up and lower the desk for a another day of work in a hot office...

Adjusting the desk for health reasons?

Then I'd need to start messing with the settings of my chair, and THAT ain't happening!

Judge uses 1st Amendment on Pokemon Go park ban. It's super effective!

Trygve Henriksen

re: In an ideal world, Pokemon Go would not be a problem

I agree with big John;

Imagine that part of a park is rented for a private gathering such as a wedding...

Then someone in an AR game company plops down a 'Legendary Pokemon' with 'Perfect' fighting stats there...

Even if none of the Zmombies drop a single candywrapper while on their way to their goal, they'll most likely ruin someone's very expensive day.

Many places that are 'open to the public' can be rented for events. In fact, many of them need that extra income to pay for the upkeep. If events gets disturbed by AR gamers, it will 'get known' and less events will be held at those ventures.

There definitely needs to be permits.

Bring it BACK... with MODs! Psion 5 storms great tech revival poll

Re: It's the keyboard.

I found that on the S5/S5mx you needed to keep the PDa on a table or other stable surface to get up to speed, but on the S3/S3a/S3c/S3mx, you held it in both hands and typed with your thumbs, without the need for something to rest it on. And you could type nearly as fast on that.

The S5 keyboard had a certain Wow factor, though. Made it look 'Professional', really.

And the keyboard on the netBook... Still miles ahead of some of todays laptops.

I actually prefer my S3a over my S5... Over double the runtime, silly low quiescent power drain(1ma/hour). It just works.

Then again, I also like to bring out my MC400 for long writing sessions, too.

(I need to finish building the Li-ion battery pack for that one. The Ni-cad pack only lasts 20hours)

Jacket... because, guess which one is in my pocket?

Siena, S3a, S3c, Workabout, Revo, S5, Oregon Scientific, or the Geofox One?

OK, not the Geofox. It's a bit too large. It stays near my netBook.

All right, trick question. Of course it's my Organiser II LZ64.

Still got a floppy drive? Here's a solution for when 1.44MB isn't enough

Trygve Henriksen

Re: Only real use for this one....

Those machines have dust covers and seals everywhere to protect them from dust. I really hope that the $300 PC you set up beside it is similarly protected...

The $15 adapter will fit where the old 3.5" drive sat, so is protected from dust.

Only real use for this one....

Instead of a $15 version from eBay(I have one of those already) is to 'network' old CnC machines and robots that has a 3.5" drive but a dedicated controller that's not 'smart' enough to handle a network.

That is, if it's easy to make and transfer a 'floppy image' to this drive over ethernet.

But the fact that it seems you have to order it with a fixed IP... sucks if you later reconfigure the network...

Network box that doesn't support DHCP = Fail.
